Hello All - I am set to go look at a 2004 X-star in a couple of days. It has the 350 HP MCX engine with 450 hours. Are there any specific things to check for on that engine? Anything on other parts of the running gear?

The guy has owned it for 6 years, but said that he has never done any tune-up to it. Also, has never changed the impeller. He said that the local Mastercraft dealer has always done the winterization. Wouldn't the dealer have suggested at least changing the spark plugs during those 6 years? Seems like the dealer would have definitely wanted to change the impeller. The seller doesn't seem overly mechanical, so it maybe something the dealer has done and he just didn't know it. I have asked him to bring me all of his service records.
